When the head of a public interest group (like, say, EWG) receives a threatening letter from one of the nation's top industry lobbyists, it generally means he's done something right. On January 27, 2011, Joseph Doss president of the International Bottled Water Association demanded that Environmental Working Group president Ken Cook and his organization stop ranking and rating various bottled water brands.

A survey of websites and labels of more than 170 bottled waters sold in the U.S. found only three – and only one of the top 10 domestic brands – that give customers information about the water’s source, the method of purification and any chemical pollutants that remained after the water was treated, according to a new report by Environmental Working Group (EWG).

You've seen The Story of Stuff, right? That short and sweet video explanation of our "consumption problem" and what we can do about it? Well Annie Leonard and the gang at Free Range Studios (plus a few great partners, including EWG!) have done it again. This time about our bottled water problem.

Last year we took a close look at 100s of bottled water labels to see how good (or bad) manufacturers are at sharing important information with consumers - like my mother, who buys it by the box (me = biting tongue; gotta pick your battles, right?

An Environmental Working Group (EWG) investigation of almost 200 popular bottled water brands found less than 2 percent disclose the water’s source, how the water has been purified and what chemical pollutants each bottle of water may contain. Just 2 of the 188 individual brands EWG analyzed disclosed those three basic facts about their water.
